You should deal with the problem first, small things can make a great difference to the condensation problem. You should look at roof vents first in the Arctic, if it is really bad then a moisture activated fan to extract moist air and improve air flow You should also check that the gutters are clear to ensure that water is not overflowing, and if you have loft insulation that this has not been laid right to edge of loft, if it has then you will need to pull it back to get air flow through attic .
